ConnectIQ Toybox::Math broken trig functions

Former Member over 10 years ago

The Math trig functions are spewing garbage, e.g

// Using .....



for( var i = 0; i < 10; i++ ){

    Sys.println( "sin " + i + " = " + Math.sin(i).toString() );

}

produces

sin 0 = 0.000000
sin 1 = 0.841471
sin 2 = 0.909297
sin 3 = 0.141120
sin 4 = -0.756802
sin 5 = -0.958924
sin 6 = -0.279415
sin 7 = 0.656987
sin 8 = 0.989358
sin 9 = 0.412118

You're not expecting it to take degrees, are you? It probably takes radians just like other languages. For example

mbp13$ perl -e '$x = sin(9);print "$x\n"'
0.412118485241757

No, no, no, ......yes. Thanks.

A bit more news. Part of the reason I was struggling was because I was trying to create a fillPolygon with too many points. It would seem to me that it can only handle 64 points ( [x,y] = 1 point ).

That's correct - we do have an upper limit to fillPolygon. We will update the documentation to reflect that.
